IMPROVEMENT IN OATMEAL-MACHINES.

Specification forming part of Letters Patent No. 208,684, dated October R, 1979 application filed May 8, 1878.

To all whom it may concern:

Be it known thatwe, FRANK W. KREMER and THOMAS G. WILLIAMS, both of Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Oatmeal-Machines, of which the following is a full, clear, and exact description.

Our invention relates to certain improvements in machinery for cutting oats for producing what is commonly designated oatmeal.

The invention consists in a tubular head, constructed as hereinafter described, through which the oats are fed to a cutting mechanism,

the tubes of said head being kept full of oats at all times, so as to insure a constant supply to the cutters, the oats being fed through the tubes to the cutters one at a time from each tube, so that no whole oats can escape.

The invention also consists of a feeder-head constructed of tubes, and hereinbefore denominated a tubular head, the receiving ends of which are inclined or cutoff at an angle, so that the oats falling from the hopper may be more readily forced into the tubes by a brush, and be fed thence to the cutter.

The invention further consists in a brush rotated over the tubular head, and serving to force the oats, ends up, into the tubes.

The invention further consists in the combination, with a tubular head, of a-head provided with rods adapted to be inserted in the tubes for cleaning them or removing obstructions.

The invention consists, finally, in a feeder composed of divided or other annular partitions, recessed or corrugated, so as to receive between them and embrace the feedingtubes.

In the accompanying drawings, illustrating our invention, Figure 1 is a central vertical section Fig. 2, a bottom-plan view of the cutter and tubular head, Fig. 3, a top view of the grating; Fig. 4, a plan of parts of the annular' partitions, showingthe recesses or corrugations. Fig. 5 is a side elevation of a difierout form of cutter and platform, the latter a substitute for the grating of Figs. 1 and 3 Fig. 6, a top view, and Fig. 7 a bottom view, of the same; Fig. 8, a partially sectional side elevation of the tubular head in part, the

brush, and the modified form of cutter and platform, illustrating the operation.

The letter A designates a bed-plate having a central annular recess, in which rests a cylindrical feeder, B. This feeder is composed of rings a b and tubes 0, all bound together by a band or strap, d. The outer ring, a, has semicircular recesses 0 (see Fig. 4) upon its inner face, and the several rings 1) have similar recesses f upon both faces, and these several rings are concentric, and gradually diminish in diameter, so as to fit one within the other. For convenience in fitting up a feeder constructed with these rings, they maybe divided into two or more parts. They may also be made entire or of one piece.

The tubes 0 are placed within the cylindrical openings formed by the recesses of and f f when the rings are brought together; andwhen'the band (I is drawn together, as by a tighteningscrew passing through flanges upon its ends, the rings and tubes will be firmly united to form a complete device.

The upper ends of the tubes 0 are beveled, as seen in Fig. 1, so that as the oats fall from the hopper they will enter the tubes after the manner indicated in Fig. 8, the lower end being in the lowest edge of one tube, while the upper end rests upon the upper or highest edge of the adjacent tube until swept into the tube by a brush, hereinafter specified.

The center of the feeder B may be provided with a sleeve, g, through which the operatingshaft 0 passes. This shaft also passes through a grating or slotted platform, D, arranged beneath the feeder or tubular head B, and ad justable relatively thereto by set-screws h in the bed A, and connected with ears 6 of the grating.

Between the bottom of the tubular feederhead and top of the grating, and upon the shaft 0, is arranged a knife or cutter, or a number of knives or cutters, E. These cutters E revolve with the shaft, while the feeder and grating are stationary.

As shown in Figs. 5 to 8, the cutters may be fixed upon a platform, D, revolving with the shaft. In this case the platform will be solid, and takes the place of the grating, the only openings in it being beneath the knives E. These knives E are secured to the plat- 'a'p iro iriate framing. and its 1 1 by power sui't abl y a ppl otherwise.

oats.

The mechanismdescribed i red the are fall in an upright or longitudinal positioiuand their ends rest upon the grating, (or platform l),) where the knives meet them and crush or cut them, so as to form oatmeal. The knives are arranged to strike the grain at an angle of about t'ortv-tive degrees with a shears-like cut, and, when severed, the pieces fall through the grating or platform and escape at the delivery-chute. The fineness ot' the meal is regulated by adjusting the grating or the knives E, by means of the set-screws, relatively to the bottom of the tubular head, the eli'ect of a close proximity of the two being that the oats proieet but a little from the tubes, when they meet the grating, and are hem-e cut fine, while the farther the grating is removed from the feeder the greater the projection of the oats. and consequently the coarserthe resultant meal.

By the employment of the tubular head a constant and full supply of oats is kept for the cutters, the tubes being always full, and this will be found adecided advantage over that form of oatmeal machines commonly used, where the feeder is a fiat perforated plate, for in this latter form the falling through of the oats to the cutter is a matter of chance, and not positively governed by mechanism, as in ours, so that by our machine more meal can be made in a given time, and the machine ean be run faster and with less attention.
